Preheat oven to 350 degrees F.
In a large mixing bowl, whisk together wet ingredients. Add dry ingredients and stir until thoroughly combined.
Fold in chopped macadamia nuts and white chocolate, if using. *Option to leave out white chocolate and instead, melt and drizzle over the top of the macadamia nut cookie once they're done baking.
Use a cookie scoop or spoon to place batter on parchment paper covered cookie sheet. Dough will not expand in diameter, so be sure to press down a bit!!
Bake for 11 minutes. Enjoy!
